Dear experts, I have recently encountered a strange problem. After the board is powered on, the boot loader starts normally, but there will be problems when entering the app, and the program cannot wo
DC-DC chips have current control mode and voltage control mode? How to understand?
Question 1: Is the voltage control mode understood as constant voltage control? Is the current control mode understoo
As shown in the figure below, there are a few points that I don't quite understand: 1. The common-mode signal of the common-mode drive comes from the voltage division of two 2MΩ resistors to obtain th
The switching power supply with 220V AC input and 24V4A output has an output voltage of about 42V when it is unloaded and lightly loaded, and the power supply itself generates a lot of heat. The power
The basic unit of a register is a D flip-flop, and a D flip-flop stores a binary number. The question is, how does a D flip-flop, that is, a register, store a binary number, what is the storage proces
